Intravitreal bevacizumab for treatment of choroidal neovascularization due to pathological myopia appears to be effective, according to a pilot study.

Over 1 year, Japanese researchers looked retrospectively at 63 eyes of 63 patients with myopic CNV who were given intravitreal treatment with Avastin (bevacizumab, Genentech).

Between one and six treatments of 1 mg of bevacizumab were given in the first 12 months, resulting in decreased size of myopic CNV (P < .01) and improved best corrected visual acuity (P < .01). In 25 eyes, BCVA increased more than three lines; in three eyes, BCVA decreased more than three lines; and in 35 eyes, BCVA was unchanged.

Active leakage was monitored by fluorescein angiography, which showed 30 eyes with ceased leakage, 28 eyes with diminished leakage and five eyes with no change.

"Although the current study lacked a control group, [intravitreal bevacizumab] seems to be an effective treatment for [myopic] CNV after a long-term," the study authors said.
